I haven't been modding Oblivion as long as I've been modding fable, but I still have a fair share of mods. That doesn't mean they're spectacular, but one in particular, the iRune, has been pretty popular. To see a description, link to download, and screenshots, and maybe even video, click the mod name.

• The Heartbreaker Saber
• The Carnival of Savings!

While the next one isn't really a mod, it's an application, I'm going to put it here anyway. The page is in dire need of cleanup, but I promise it's a good app if you are an Oblivion modder: XML-MSG
